Diagnosing and Rebuilding a Server System After a Major Failure

Description / Abstract

Submitted to the Department of Mathematics and Computer Science in partial fulfillment of the requirements for the degree of Bachelor of Arts

After a power failure, the Computer Science Lab server system failed to connect to the outside network. After examining the individual systems, it was discovered that the Network File System Server, which contained all the important virtual machines, was down. Using a Linux Rescue Disk and an external hard drive, all the information from the NFS server was backed up to troubleshoot the system safely without loss of data. After running through a multitude of troubleshooting steps to repair the system with the current system intact, it was decided that the server had to be completely wiped and reset. The new operating system was installed and the redundant array of independent disk structure of the server recreated. The virtual machines were restored from the backup and the network restored. Finally, the shared network drive was recreated on which students could store files and run web pages. The drive also contained specific folders on which faculty and researchers could store files and images. All the lab systems were restored to pre-power failure level and, in some cases, improved.
